Hi Yury,
Oh... that's a lot of files! Yes, that kind of autocomplatetion might
require some kind of custom Javascript solution. Although, if the goal is
to have a wiki page for each of those files, another option is to just
create a page for each file automatically, with the first 2-4 of those
template fields already filled in. You could do that with the Data Transfer
extension, or a custom script; the latter might be better, given the
massive size of the data.
